Answer: |p-72% |≤ 4%
Step-by-step explanation:
Let p be the population proportion.
The absolute inequality about p using an absolute value inequality.:
, where E = margin of error, = sample proportion
Given: A poll result of 72% with a margin of error of 4% indicates that p is most likely to be between 68% and 76% .
|p-72% |≤ 4%
⇒ 72% - 4% ≤ p ≤ 72% +4%
⇒ 68% ≤ p ≤ 76%.
i.e. p is most likely to be between 68% and 76% (.
The answer to your question 29 is E 935,00. The way how I got this answer by multiplying 55 and 17,000 and by that the is E. For question 30 the answer is H. The way how I got this answer is by knowing twice means 2 times so by that H was the only one with 15+2n so by that I knew that was the answer.
Hope this helps:)
Answer:
The new center is the point (-x, y)
Step-by-step explanation:
When you reflect a point across the y-axis, the x-coordinate changes to its opposite (additive inverse).
See the attached image for an example.
The circle on the right has center (3, 1). When reflected across the y-axis, the reflected center is (-3, 1).
THE ANSWER WOULD BE 16 BECAUSE 6 * 3 EQUALS 18 AND 18 MINUS 2 EQUALS 16 THERE GOES YOU ANSWER
